These forms remind me of both geodes and even more so, seashells. They are high-fired porcelain with wild iron inclusions that I have collected. The reactions vary depending upon the chemistry of the surface treatment in conjunction with the iron inclusions and the manipulation of the reduction firing process. Most often I fire in a gas reduction kiln but in some instances switch to a wood-fired kiln to achieve ash deposits with subtle flashing.
It is a true conversation between myself and each piece as I push the bounds of what the clay body can withstand while also responding to those limits. Many pieces do not survive the intensity of the process but those that do contribute greatly to the ephemeral and delicate beauty of this collection.
Currently, I fire my work at the Watershed Center for Ceramic Arts in New Castle, Maine where they have a variety of kilns to chose from.
Sizes of these forms range from 4-13" x 3-13" (compositions are larger, with heights up to 18"). These works are priced from $45 to $500 based upon size.
An intriguing direction I am currently pursuing and intend to have available in other forms this fall is what I call Ceramic Iron. These forms are porcelain-based with an extremely high iron content reduction fired to cone 11.
